I know I can make the chirps louder by cutting the (black?) wire on the siren. I read that somewhere. But it's not the chirps I want louder, it's the siren.

I forget where I park a lot, so I press the button a couple times and it gives a quick siren blast. But I can't really hear it unless I'm already pretty close (like a few cars away.) And the horn doesn't honk like on some other alarms I've seen.

I was thinking of adding a siren. Does it have to be a Viper 5900 siren or is there some kind of aftermarket siren I can get? I know NOTHING about car alarms, so I don't know if one siren is the same as the next (amperage, power requirements, hookup... whatever)

Also, the placement of my siren (I believe) is part of my problem. With my hood popped, it's MUCH louder. I have a 99 Tahoe. The siren is under the ECU. (Have to look again, I think it's the ECU.) It points right into a piece of metal. It could be moved back some I think, which would help. Or just relocated completely. But I'm scared to mess with it and don't want to have to pay the install guy to do it if I don't have to.

Any idea what DB rating the stock Viper 5900 siren is? Just so I know where to start.

I got the $50 siren from BB (they have it in the back, go ask the installer for one). I'd estimate it's audible from a mile +

Add horn honk output and that 128db siren will be fine with the horn going off as well.

Your right he could go right ahead and ground the siren wire, destroying the brain or the relay that you isolated it with, which then would run back to the brain, Horn is the solution here. get it hooked up,
